12Pcs HVAC Repair Kit, Air Conditioner Tube Expander Swaging Tool, Manual Pipe Swage Tool With Expander Boring Drill Bits for Soft Copper Tubing 1/4'' to 7/8''

I got these for one job and they worked great. I wish there was no finish on the working end as that burns off on my copper line. So for that use it on a test or scrap piece to remove the finish first. Other than that works as intended

Bought this for my husband as I always buy on Amazon and he was so happy, it fit perfectly on his drill and having all different sizes all at once was like candy in a candy store, the price was amazing and they were super easy to use, the metal is strong on product no shabby cheap stuff

Work very well, wish it had a 5/16 in the package. Make sure if you holding the tubing with your hand you use a wet rag cause it does get the brass hot.

My husband bought this to use on a job as a plumber- expanding a copper pipe. He said the boring bit fit perfectly into his drill and worked exactly how it was supposed to. The bits are easy to use. He only needed the 3/4” piece for work but the set was such a good deal and came in its own case for easy storage in his van. The set is made of thick metal and looks sturdy and strong. I was surprised how heavy this set was. He got the 6 piece set. One thing he said was how expensive these individual boring bits/sets are in store and how good of a deal this set is. He didn’t want to buy an expensive set bc he’s never needed this tool before and it’s unlikely he’ll need it again. Husband said he recommends this set but emphasized he’s not using it constantly or in ways that really push the boring bits to the limit.

If I could do 0 stars I would,first time I used it in snaps in half do not buy this Chinese BS

The small ones worked good but the larger ones didn’t swedge the copper very well

Don’t work as good on anything above 3/8” as it does on 3/8”

Was not expecting this I was not trying to return this item.

Producto de excelente calidad.

Only needed the 5/8 size but cheep.for the full set. Used it on some copper tubing to flare the end and worked well.
